What is meant by an equivalent resistance?
The equivalent resistance is defined as a common point or node where the total resistance is measured in a series or parallel arrangement (in either the whole circuit or in a fraction of the circuit). The equivalent resistance or multiple resistors is defined between two terminals or nodes of the electrical network.
How do you find the equivalent resistance between points a and B?
Now, 5Ω,56Ω and 3Ω are connected in series,so their equivalent resistance is given by : R=Req+5Ω+3Ω=548Ω→ equivalent resistance between A and B.
How do I find the equivalent resistance?
Equivalent resistance can be found if you know the individual resistance values and the source voltage. By calculating each branch current, adding the branch currents to calculate total current, and dividing the source voltage by the total current, the total can be found.
What is the formula for equivalent resistance?
The equivalent resistance of a parallel circuit is found by the general equation Req = 1 / ( 1/R1 + 1/R2 + … 1/Rn) The total power consumed in a parallel circuit is equal to the sum of the power consumed by the individual resistors.
What are the methods of determining Thevenin resistance?
The different methods of finding Thevenin’s Resistance or internal impedance are as follows: For Independent Sources – The most common method of finding the equivalent Thevenin’s Resistance (R TH) or the internal impedance of any linear, bilateral network containing independent current or voltage source is to deactivate the source by its internal resistance .
What is the equivalent resistance through the entire circuit?
The equivalent resistance is defined as a point where the total resistance is measured in a parallel or series circuit (in either the whole circuit or in a part of the circuit). The equivalent resistance is defined between two terminals or nodes of the network.
